Light Gauge Metal Roof and Wall Panels Installation Guide for Delta Rib, Delta Rib III, Nor-Clad®, Strata Rib® & 2½ Corrugated

In addition to weather tightness, long life, good looks and economy, ASC Building Products’ light gauge Roof and Wall Panels are designed with ease of installation as a primary consideration . this guide is intended to help the installer achieve a high level of quality in the finished product . Please do not hesitate to contact an ASC Building Products representative for assistance .

Important NoticeBe sure to read this manual in its entirety before beginning installation.

this manual is provided to the customers of ASC Building Products as a guide to assist in the installation of light gauge Metal Roof and Wall Panels . Use for any other purpose is prohibited . this manual remains the property of ASC Building Products .

these instructions contain suggested application procedures only and cannot replace the need for good common sense and experience . Responsibility for conformance to state and local building codes, as well as any other ap pli ca ble project requirements rests with the installer, as does the responsibility to observe reasonable safety procedures .

ASC Building Products assumes no responsibility for any problems which might arise as a result of improper installation or any personal injury or property damage that may occur with the product’s use .

Introduction

Screw Gun: Clutch type screw gun with depth locating nose piece allowing variable torque settings is recommended to insure proper installation of the screws . the following sockets will be required: 1/4” and/or 5/16” hex .

Snips: for miscellaneous panel and flashing cutting requirements . three pairs of snips will be required for left edge, right edge, and centerline cuts .

Electrical Metal Shears: Used for general metal cutting, such as at the hips and valleys

Note: Some erectors prefer to use circular power saws with metal cutting abrasive blades. While the use of power saws may be faster, there are some disadvantages that must be considered: (1) The edges of metal that have been saw cut are

jagged and unsightly, and are more likely to rust than sheared edges.

(2) Saw cutting will leave small particles of metal on the panel surface that will rust and damage the panel finish if not completely removed.

Chalk Line: Used to assist in the alignment of panels, flashings, etc

Neoprene Mastic Tape: 1/16” x 1/4” roll of tape used for installation of inside and outside profile closures and panel side laps .

Butyl Mastic Tape: 1/16” x 1/2” roll of tape used for prevention of water infil-tration in flashing to sheet metal applications and Super-Span® panel-to-panel sidelaps .

Caulk: Butyl or urethane sealant used to inhibit water infiltration .

Caulking Gun: for miscellaneous caulking and sealing to inhibit water infiltration .

Blind Rivet Hand Tool: Used for miscellaneous flashing and trim applications .

Marking Tools: Indelible markers, pencils, or scratching tools .

Minimum Recommended Tools & Equipment

Note: • It is recommended that Light Gauge Roofing be applied

on roofs with a minimum slope of 3 inches per foot (3:12).

* The details contained in this guide are shown over a ply-wood substrate. Details remain the same for either a solid substrate (plywood or steel), spaced framing or intermit-tent support condition with only the fastener type chang-ing. Where spaced framing is used, perimeter supports for flashings must be considered.

** Each flashing part in this guide has been assigned a part number. Each part number contains one or two letters followed by one or two numbers, for example: (EW17). These part numbers have been provided for you to make ordering these flashing parts quick and easy.



Minimum Recommended Tools & Equipment (Con’t)Scratch Awl: Used to mark the steel .

Utility Knife: Used for miscellaneous cutting .

Electric Drill: Used to drill holes such as those required for rivet installation .

String Line: Used for general alignment and measuring .

Tape Measure: 25 foot minimum (another 50 ft . is handy) .

Locking Pliers: Standard and “duckbill” style for miscellaneous clamping and bending of parts .

Delivery, Handling and Storage

• Always check the shipment upon delivery . Check for damage and check material quantities against the shipping list . note any damaged material or shortages at the time of delivery .

• Handle panel bundles and individual panels with care to avoid damage . longer bundles and panels may require two or more “pick points” properly spaced to avoid damage that can result from buckling and/or bending of the panels . Request a copy of the long length Handling Instructions and diagrams from ASC Building Products customer service as required .

• Store the panels and other materials in a dry, well ventilated area and away from traffic . elevate one end of the bundle so that any moisture that may have accumulated during shipping can run off . Be sure that air will be able to circulate freely around the bundles to avoid the build-up of moisture . never store materials in direct contact with the ground .

• Wear clean cotton gloves when handling unpainted Zincalume®-coated panels or flashings to avoid discoloration . Rollforming die marks (which appear black), particularly at bends, will be visible .

• Wear clean, non-marking, soft soled shoes when walking on the panels to avoid shoe marks or damage to the finish . do not step on the panel seams or ribs . Step only in the flat area of the panel .

Safety Considerations

• Never use unsecured or partially installed panels as a working platform do not walk on panels until they are in place on the roof and all of the fasteners attaching the panels to the roof have been installed .

• Metal roofing panels are slippery when wet, dusty, frosty or oily do not walk on a metal roof when any of these conditions are present . Wearing soft soled shoes will help minimize slipping and help prevent damage to the painted surfaces .

• Do not walk on the panel seams or major ribs When walking on the fully installed roof panels, be sure to step only in the flat areas of the panels .

• Always be aware of your position on the roof relative to your surroundings. take note of the locations of roof openings, roof edges, equipment, co-workers, etc .

• Always wear proper clothing and safety attire. Wear proper clothing when working with sheet metal in order to minimize the potential for cuts, abrasions, and other injuries . ASC Building Products recommends safety glasses and gloves .

• Use care when operating electrical and other power equipment. observe all manufacturer’s safety recommendations .\

• Roof installation on windy or stormy days can be dangerous . Avoid working with sheet metal products on windy or stormy days .



Roof PreparationASC’s light gauge Roofing can be used in both new construction and retrofit roofing applications . We recommend the installation of light gauge Roofing over a continuous rigid substrate such as plywood, wood decking, or over in ter mit tent supports . Contact ASC for additional information .

the following steps need to be taken to prepare the roof for installation of light gauge Roofing panels:

New Roofs:

1 . Make sure there are no nails or other objects protruding from the substrates that might puncture the underlayment or the roof panels . Clean all debris from the roof .

2 . Check all details for possible roof penetrations which must be added to the deck prior to roof panel installation .

3 . Cover the entire roof deck with a minimum of 30 lb . asphalt-saturated felt paper . Some synthetic underlayments may be used in place of felt with our roofing . Installer must ensure they meet the minimum standards of 30 lb felt and that the manufacturer has approved them for use with metal roofing . for applications over spaced framing other types of moisture barriers may be required . Begin at the eave and roll the felt horizontally (parallel to the eave) . Allow each con sec u tive course to overlap the previous one 3 inches . overlap the end a minimum of 6” when starting a new roll of felt . Areas of felt paper that have been torn or cut should be replaced or repaired prior to installation of the metal roof . (See illustration #1) .

4 . Place an alignment line along the gable end where the first roof panel will be installed . This line must be parallel to the gable edge of the roof deck and square with the eave line. Check the roof for squareness by making a 3’ line across the eave . (See illustration #2) .

Completing the 3’ x 4’ x 5’ triangle should place the 4’ edge of the triangle parallel with the gable . the first roof panel will be placed parallel with this line . Slight variations or out-of-square conditions up to 3” can be covered by the gable trims shown on page 18 .

5 . It is very important to measure the entire length of the roof from gable to gable . Correct placement of the panels will allow the panel’s ribs on each side to be covered by the gable flashing shown on page 18 . this will create a symmetrical appearance on both gables . Should this be impractical, the adjustable gable detail on page 29 can be used .

Note: In areas where snow, ice, and heavy rain conditions exist, a high temperature cold-applied rubberized underlayment should be used in lieu of felt in the valleys. Felt on the remainder of the roof will lap over the membrane where the two meet. See Valley page 13.

Existing Roofing:Some jurisdictions will allow reroofing over existing roofing without the need for tearoff . Check with your local codes or building department for your specific requirements .

for best results, light gauge Roofing requires a relatively smooth and flat substrate . Application over rough and/or uneven surfaces is not recommended, for example, wood shingles .

If the roof is to be stripped down to the existing decking, follow the procedures for new roofs on page 4 . Be sure to check the existing roof and repair any damaged areas prior to installation of the new roof system .

Note: Do not apply Light Gauge Roofing over roofs with structural damage or trapped moisture.



The following steps should be taken when installing ASC’s Light Gauge Roofing over existing roofing:

1 . Inspect the roof for damage and make the necessary repairs to achieve a flat plane for the metal roof panels . Wood shingles should be removed .

2 . Secure any warped or loose roofing .3 . Make sure that there are no nails or other objects

protruding from the roof that might puncture the new underlayment or the new roof panels .

4 . Remove all moss and other debris from the roof .

5 . Cut off any overhanging roofing flush with the roof deck and remove all hips, ridge caps, and penetration flashings .

6 . Metal debris/shavings should be removed from the roof progressively and daily to prevent immediate corrosion and scratching of the top coat .

7 . follow the directions on page 4, #2 through #5 on roof preparation .

Notes

• The table above shows the Light Gauge panel fasteners provided by ASC Building

Products. Refer to the panel installation, flashing details, and fastener placement

pages of this manual for specific fastener usage. See page 6 for fastener spacing.

• Panel attachment screws must be long enough to penetrate through the roof decking

at least 3/8”, or penetrate solid lum ber at least one inch.

• All screws must be coated to provide protection against corrosion.

• Exposed fasteners should have sealing washers and be the same color as the parts

they attach.

• Roofing nails will also be required, but are not furnished by ASC. They are typically

used to temporarily hold a flashing in place that needs to be installed prior to panels.

• Screws must be properly driven to ensure proper seal and holding strength. Do not

under \drive or overdrive the screws. Recommended drill speed is 2000 rpm. Use of a

depth-sensing nosepiece will aid in properly driving screws.

PROCEDURE1 . Install eave trim, valley trim and inside closure prior

to panel installation .2 . Align the edge of the first panel with the alignment

line constructed along the start gable . (See page 4 item 4 and illustration #3 below.) Allow the panel to overhang the eave 1” minimum .

3 . Check the downhill end of the panel . If the panel length is correct, the panel should overhang 1” past the eave trim as shown below in illustration #4 . Also, the panel should not extend past the centerline of the ridge . (See pg. 9)

4 . After the first panel is properly aligned, fasten per the fastener placement and spacing guidelines on page 6 .

5 . lay down the second and third panels, checking alignment, making sure they are square . this will ensure that a sawtooth effect at the eave and ridge is avoided .

6 . Metal debris/shavings should be removed from the roof progressively and daily to prevent immediate corrosion and scratching of the top coat .

flashing so it overhangs the eaves 1” . (see pg. 14)• Caulk and lap the subsequent valley flashings a

minimum of 8” .• Parallel to the valley, place two rows of 1/2” butyl

mastic tape sealant spaced as shown .• the polyethylene closures cannot be installed diagonally

across a panel . At mitre cuts, use emseal closures at a right angle to the panel ribs .

• field cut the panels holding a minimum of 4” back from the valley as shown . larger valleys without the center “V”, may be required in snow country installations .

• Attach the panels to the roof and ‘thru-fasten’ along the bottom end using a #14 x 1” woodscrew

at 8” up from the valley aligned with the second row of butyl mastic tape .

• When valleys are required, install sidelap neoprene mastic tape along the sidelap a minimum of 10’-0” up from the panel edge .

Note: In areas where snow, ice and heavy rain con-ditions exist, panels may need to be held back more than 4” and the valley flashing overall width must be increased. A high temperature cold-applied rubberized underlayment should be used extending at least 3’ up from the center of the valley on each side.

Procedures• In many instances, the roof sheet will have to be field

modified (major rib removed along the gable) . See roof map on page 5 and locate “adjustable gable” . If gable trims are used in this location, and as the roof drains from the ridge, water will flow inside the gable trims shown on page 17 . the adjustable gable trim pieces shown above can assist in a proper roof in stal la tion .

• When a major rib on a light gauge panel occurs over the roof area within 3” of the edge of the gable, cut the panel and remove the major rib from the end of the sheet from the low eave to allow for the placement of the starter strip .

• Install the gable trim, extending the horizontal leg 6” uphill and underneath the eave on the portion of the roof sheet at the gable/eave intersection .

• locate the placement of the starter strip to insure that the cut edge of the roof sheet can be inserted into the 1” leg of the starter strip .

• field caulk inside the open hem and the under side of the starter strip per the detail on this page and install parallel to gable .

Note: Locate starter strip to allow proper installation of adjustable gable trim as shown.



Vent Flashing

Procedures• trim the opening in the flashing to 20% smaller

than the pipe diameter .• Slide the flashing down over the pipe .• Seal between the vent flashing and the roofing with

gunnable caulk and set the flashing .• form the flashing to fit the profile of the roof .• fasten the flashing with fasteners at 1” o .c . Refer to

the fastener selection guide on page 7 .• Penetrations occurring over spaced supports

require additional support framing .• A stainless steel draw band should be installed at

the top of the vent/pipe flashing .

• A minimum drainage area of 2” should be‚ maintained between the base of the flexible vent/pipe flashing and the roof panels’ major ribs .

• When a penetration occurs through a nor-Clad® panel sidelap, gunnable caulk needs to be installed in the capillary groove from the penetration to the ridge . this will prevent water from running downhill in the capillary groove and into the roof opening . Refer to illustration #5, above .

ILLUSTRATION #5

Note: For the best drainage when a square-based pipe flashing is used, one corner of the flexible pipe flashing should be oriented to the high-side of the roof.



Vent/Pipe Flashing Installation Procedure

STEP 1: CutCut to pipe diameter marked on flashers (this is approximately 20% smaller than the diameter of the pipe) .

STEP 2: SlideSlide the flashers down the pipe, using water to lubricate if necessary .

STEP 4: SealSeal the flashers by applying urethane/silicone sealant between the flasher and the roof . Use a large slot screwdriver to press the base down tightly .

STEP 5: Fastenfasten the flashers with weather-resistant fasteners to complete the seal .

STEP 3: Formform and bend the aluminum base of the flashers to fit the surface of the roof .

Note: For the best drainage when a square-based pipe flashing is used, one corner of the flexible pipe flashing should be oriented to the high-side of the roof.

Trim and bend the right side skylight flashing as indicated. Trim the left side in a similar fashion.

The skylight flashing will be 4” wider than the width of the curb (2” on each side). Cut a 1/8” slot in the two uphill corners of the Light Gauge Roofing Panel slightly wider than 2”, so the uphill flashing can slide through the two slots. (See illustration #6).Adjustments to the horizontal leg dimension and length of slit may have to be modified depending on the location of the panels’ major rib.
